PENCIL-SHARPENER.

SPECIFICATION forming part of Letters Patent N o. 659,527, dated October 9, 1900. Application filed August Z, 1900. Serial No. 25.695. kllo model.)

To @ZZ whom, t may concern:

Be it known that I, JAMES H. HILL, a citizen of the United States, residing at Boone, in the county of Boone and State of Iowa, have invented certain new and useful Improvements in Pencil-Sharpeners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the Same.

My invention relates to improvements in pencil-Sharpeners; and one object is to provide a Sharpener which maybe conveniently carried in the pocket without liability of inj uring the hands or clothes of the user in inserting and withdrawing same, and which is simple in construction and adapted to perform its work in a cleanly and efficient manner.

A further object of the invention is to pro- Vide a Sharpener wherein the blade is so mounted as to permit of the ready and convenient sharpening of the blade and insure a rapid clearance of the shavings and dust to prevent clogging of the blade and soiling of the pencil and fingers of the operatorand also to provide a holder of novel construction in which the cutter when not in use is effectually concealed and protected from injury.

With these and other minor objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described,and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a perspective View of a pencil-Sharpener embodying my invention, showing the cutter as arranged in use. Fig. 2 is an end View looking toward the cutter. Fig. 8 is a longitudinal section showing the adjustable member carrying the cutter or blade slipped back into the casing. Fig. 4 is a cross-section.

Referring now more particularly to the drawings, in which like reference characters designate corresponding parts throughout the several views, the numeral l designates the tubular holder or casing of the Sharpener, which is provided with a longitudinal slot 2, having offset ends 3 and 4, and may be open at bothy ends, as Shown, or open at one end only, for the reception ofthe extensible member carrying the cutter or Sharpener, as desired.

In the holder is slidably mounted a staff, plug, or bolt 5, which is cut away at its forward end to form a beveled guide-face 6 and a side guide or wing 7 and is further liattened on its under Side to form a Seat for the cutting blade or knife 8. The beveled face 6 inclines downwardly and inwardly or rearwardly toward the guard or wing 7, and the outer end or edge 9 of Said face also inclines inwardly from its outer Side toward the guard, so as to set at adiagonal angle, wit-hits inner or lower side terminating in rear of the point of the guard which projects outwardly and forwardly therefrom. The knife Sis adjustably secured by means of .a set-screw 10, projecting through an elongated slot 11 therein and entering a threaded bore in the plug, and the front cutting edge 12 of this knife also extends at a diaganal angle in conformity withl the Said diagonal edge 9 of the beveled face of the plug. The plug or bolt is reduced in rear of the beveled face thereof to form a shank 13, which is tted within a' sleeve 14, which Slides within the case or holder 1, and the shank is provided with a series of threaded holes 15, either one of which is adapted to register with an opening 16, formed in the Sleeve. The sleeve and bolt are adjustably connected with each other and with the holder through the medium of a Set-screw 17, entering one of the holes 15, the opening 16, and the slot 2 in the tubular case or holder, and also through an opening in an adjusting band or ring 18, slidably mounted on the holder. By this construction it will be seen that the bolt may be inserted in and projected from the holder by an endwise sliding movement and locked in either open' or'closed position by giving it or the holder a partial rotative movement to bring the Set-Screw 17 in the offset 3 or offset t of the slot 2. The ring or band 18 is employed as a linger or thumb piece to Slide the plug in and out of the holder. When the plug is moved inward to the fullest extent, it is held from sliding, and the cutter-blade is concealed and protected, So as to prevent injury thereto and IOO cutting of the users hands and clothes in inserting and removing the Sharpener from the pocket.

In employing the Sharpener in practice to sharpen the end of the pencil the plug is slid outward to the desired extent to expose the beveled guide-face 6. The Sharpener is then held in one hand and the pencil in the other hand and the end of the pencil rested on the y guide-face 6 with the body of the pencil projecting rearwardly and upwardly above the holder. over the cutting edge of the blade the wood may be rapidly eut away on a desired taper to expose the lead and the latter then pointed as desired. In moving `the pencil it is held against the guard 7 and guided by saidguard and prevented from slipping olf the beveled face. The shavings and dust from 4the graphite removed by the blade are caused :by the inward inclination of the guide-face 6 to `feed by gravity in a diagonal direction toward Vthe guard 7 and inner side of the diagonal edge 9 of said face and to discharge beneath the projecting point of the guard, which insures rapid l clearance and the prevention of choking of the blade and soiling of the `wood of the pencil and fingers of the user. By means of thel series of holes I5 the bolt may be adjusted to project to a greater or less extent from the holder; but I may dispense with the use of all but one of the holes and also with the sleeve and increase the length and diameter of the plug to compensate therefor, if desired. The blade as mounted `is adapted to be conveniently sharpened by sliding out the plug and rubbing the edge of the blade on a Whetstone in an obvious manner. The advan- By now drawing the pencil back` ta ges of the invention will be fully understood from the `foregoing description.

Changes in the form, proportion, and minor details of construction may bemade within the scope of the invention without departing from the spirit or sacrificing any of the ad'- vantages thereof.

Having thus fully described my invention,

vwhat is claimed, and desired to be secured by I. In a pencil-Sharpener, the combination of a tubular case `or holder provided with a longitudinal slot having oiset ends, a staff or plug slidably mounted in the holder and provided at one end with a beveled guide-face and side guard, a ring `or band slidably `mounted on the holder, and a screw `or pin .passed through the ring `and slot 4and `connected to the plug, substantiallyas set forth.
